Abstract (en)
[origin: WO0165182A2] A pressure proving gas valve insures safe and efficient operation of a fuel-burning appliance by monitoring combustion airflow and appropriately controlling the valve based upon this airflow. An airflow sensor is incorporated into a pressure proving valve housing itself thus providing integrated solution for the control of the combustion process. Consequently, when heat is called for, no fuel is provided to the combustion chamber unless appropriate combustion air is sensed. Further, by monitoring the actual airflow, additional control capability is provided. That is, a variable speed blower associated with the combustion apparatus can be controlled to provide very precise fuel to air mixtures.
[origin: WO0165182A2] A pressure proving gas valve (10) insures safe and efficient operation of a fuel-burning appliance by monitoring combustion airflow and appropriately controlling the valve based (22) upon this airflow. An airflow sensor (26) is incorporated into a pressure proving valve housing (20) itself thus providing integrated solution for the control of the combustion process. Consequently, when heat is called for, no fuel is provided to the combustion chamber (12) unless appropriate combustion air is sensed. Further, by monitoring the actual airflow, additional control capability is provided. That is, a variable speed blower (60) associated with the combustion apparatus can be controlled to provide very precise fuel to air mixtures.
